  • Publication number: 20090212109
    Abstract: An arrangement is provided for reading information from a disposable with an information carrier which comprises a code formed by graphic symbols for the machine-readable provision of information and an optical reading device for the code which has a light source and a sensor. Generally according to the embodiments of the present invention, the information. carrier comprises a code applied to a transparent or translucent substrate which can be read under stationary transillumination by means of the light source as a shadow image projected onto the sensor.

  • Publication number: 20090116015
    Abstract: A system for determining the concentration of an analyte in a liquid sample comprising a detection unit for detecting light intensities which are radiated from subareas of a detection area of a test element as well as an evaluation unit which determines a frequency distribution for the detected light intensities wherein the frequency distribution has at least one first maximum caused by unwetted subareas or at least one reference area and a second maximum caused by wetted subareas and selects at least one light intensity on the basis of the frequency distribution and determines the concentration of the analyte from the at least one selected light intensity.

  • Publication number: 20080180652
    Abstract: Test element analysis system for the analytical investigation of a sample, in particular of a body liquid of human beings or animals, comprising test elements (2) with a carrier film (5) and a test field (7) fixed to the flat side (6) of the carrier film (5), the test field (7) containing a reagent system the reaction of which with the sample (21) leads to an optically measurable change in the detection zone (24) which is characteristic for the analysis, and an evaluation instrument with a measuring device for measuring the optically measurable change.

  • Publication number: 20080087819
    Abstract: The invention relates to a method for analyzing a fluid sample, such as a body fluid sample in which, after loading a test element with a sample of a fluid, the fluid sample passes into a detection area of the test element and spreads out in the detection area, and in which a filling extent which characterizes the spread of the fluid sample in the detection area is determined using a photometric measurement of the fluid sample in the detection area, wherein the photometric measurement is carried out by means of a first light which is irradiated onto the fluid sample in the detection area, said first light having a first wavelength for which, when at least one chemical parameter of the fluid is varied, the fluid has an essentially constant optical behaviour with respect to at least one spectroscopic parameter selected from a group of spectroscopic measurement parameters consisting of absorption, transmission, remission and fluorescence, and wherein the at least one chemical parameter of the fluid comprises at
